3-3. Description

○

Symbol (-) display

This symbol lamp will be lighted when the output voltage is become less than

0V.

○

Voltage display

Output voltage is displayed as in 4 Digit -7 Segment LED.

When output voltage is over 10V or below -10V, it will be displayed as +/-

10.00 and the rest section will be displayed as in +/- 9.000V.

○

Zero Hand-operated control volume

It is a volume to control the offset of residual quantity after finishing the auto

zero control.

Control range is within ± 1V.

○

Zero auto control switch

Use this switch to carry out auto zero control.

When this auto switch is pressed, "Auto" will appear on the LED and then

zero will be set.

○

Bridge voltage selecting switch

This switch is to select the bridge supply voltage.

You can make your selection for the supply voltage among DC 1V, 2V, 5V,

7.5V, 10V.

○

Bridge voltage fine control volume

This controls establishing bridge voltage precisely.

○

Bridge voltage senscing selecting switch

When select by EXT mode as switch to compensate bridge

Cable's resistance change, bridge voltage by Cable length change moves

automatically and is corrected.

○

Internal CAL Bridge resistance selecting switch

This switch is to select the bridge resistance while you are doing bridge

calibration.

○

CAL Strain value switch

It is a shunt switch to calibrate the bridge in two different types - 2000µ and

200µstrain.

○

GAIN selecting switch
